|---|---|---|---|
| CVE-2025-69421 | 6.5 | medium |
CVE-2025-69421. CWE-476: NULL Pointer Dereference. Issue summary: Processing a malformed PKCS#12 file can trigger a NULL pointer dereference in the PKCS12_item_decrypt_d2i_ex() function. Impact summary: A NULL pointer dereference can trigger a crash which leads to Denial of Service for an application processing PKCS#12 files. The PKCS12_item_decrypt_d2i_ex() function does not check whether the oct parameter is NULL before dereferencing it. When called from PKCS12_unpack_p7encdata() with a malformed PKCS#12 file, this parameter can be NULL, causing Denial of Service impact. The vulnerability is limited to Denial of Service and cannot be escalated to achieve code execution or memory disclosure. Product is affected, if a privileged user uploads a malformed PKCS#12 certificate via web interface or if PKI client functionality is configured.
